20256	PHP SESSION issues with Chrome	aternus		"Hey everybody,

After a long time of breaking my head on why SESSIONs were broken with Chrome, I've found a solution.

'''The ISSUE:'''
Wordpress rewrite doesn't report 404 properly for a missing favicon (more elements might be involved).

'''SCENARIO:'''
Plugin generates CAPTCHA and stores the value inside the $_SESSION array.
Because of the missing 404 header/wrong rewrite rules, Chrome makes several requests resulting in CAPTCHA being refreshed without user input submit.

'''FIX:'''
Send 404 header for missing files.
